Abstract Cucumber is one of the important greenhouse vegetables．Because of its fragile root
system，good atmosphere and shallow distribution，its adaptability to saline environment is lower．
Soil salinization has become a main limiting factor affecting its yield and quality．This paper described
the response of cucumber to salt stress and its basic salt tolerance mechanism from perspectives of
photosynthesis，ion toxicity，cell membrane and antioxidant enzymes，etc. angles；introduced the
research progress on cucumber salt tolerance related genes including genes related to Na+/K+ regulation，
plant hormone regulation and ROS regulation；and also pointed out problems existing in studying salt
tolerance of cucumber，aiming at providing theoretical references for revealing cucumber salt tolerance
mechanism and breeding of salt tolerant cucumber varieties
